I own marantz receiversâ NR1501range and it is causing problem. I am planning to replace my marantz receiver with new one, but do not have any idea about new arrival. I am looking for the 1601, but donât have any latest news about it. I inquire the store but they told me that they have no stock of these receivers. Can anyone tell me about the marantz receiversâ and their availability? If marantz is launching its new product please let me know.
